A backpacking pack is more than just a bag—it's your mobile basecamp. The right pack distributes weight evenly, reduces fatigue, and keeps your gear organized.
Explore outdoor backpacks that match your adventure style.
For day trips, a lightweight day pack might be all you need, but for multi-day treks, you'll want a dedicated hiking backpack with proper suspension.
In this guide, we'll cover the key factors: capacity (liters), fit (torso length and hip belt), features (pockets, hydration compatibility, access), and materials (nylon, polyester, and eco-friendly options).
We also highlight top picks for ultralight outdoor gear enthusiasts and those who need extra durability for overnight camping trips.

Fit Is Everything: Adjusting Your Backpacking Pack
Torso Length
Measure from your C7 vertebra (the prominent bone at the base of your neck) to your iliac crest (top of your hip bones). Most packs are adjustable, but get the right size range.
Hip Belt
80% of the weight should rest on your hips. The hip belt should wrap around your iliac crest, not your waist. A well-fitted belt prevents shoulder strain.
Load Lifters
These straps angle from the top of the shoulder straps to the top of the pack. When tightened, they pull the load closer to your back, improving balance and posture.
